Strait of Hormuz traffic returns to normal by December 31?

Platform comparison

Market context

The Strait of Hormuz, through which roughly one-fifth of global seaborne oil transits, has experienced significant disruption since late 2023 owing to Houthi attacks on commercial vessels and subsequent military interventions. Recovery to a 7-day moving average of 60 daily transit calls—the threshold for this market—would represent a return to pre-disruption throughput levels. The market's 82% YES probability reflects trader confidence that normalisation will occur within the next two years, though the specific settlement mechanism tied to IMF Portwatch data introduces a technical dependency that differs from how comparable geopolitical shipping markets are structured on Kalshi versus Betfair, where settlement often relies on news wires rather than official statistical releases.

Historical precedent suggests major shipping corridors recover within 18–24 months of conflict de-escalation. The 2022 Black Sea grain corridor blockade saw traffic rebound to near-normal levels within months of the deal's announcement, though the Suez Canal blockage in 2021 took longer to clear. Current catalysts include ongoing ceasefire negotiations in Yemen, US naval presence in the region, and insurance premium adjustments that reflect perceived risk. Traders should monitor announcements from the International Maritime Organization and shipping indices; recent reports from Lloyd's List indicate some rerouting traffic has already begun shifting back through the Strait as perceived threat levels fluctuate.

The probability divergence across platforms reflects differing trader bases: Polymarket's implied odds (approximately 4.5–5.0 decimal) and Kalshi's binary structure both accommodate this market, though Kalshi's US-focused KYC requirements and Betfair's European liquidity pools may price geopolitical shipping risk differently based on regional exposure to Middle Eastern trade flows.

Methodology

We read Strait of Hormuz traffic returns to normal by December 31? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
